CHARLES HEATON, on NEW YORK, N. F. ROWLAND, or en Specification formingpart To all whom it may concern:

Be it known tha the city, county,

part of this specificati t 1, CHARLES and State of Ne Y., ASSIGNOR TO EEN POINT, NEW YORK HEATON, of w York, have on, in which- Figure 1 represents a plan, and Fig. 2 a lonelevation, of a piece of ordgitudinal' sectional nance constructed sponding parts.

The object of th according to my invention is invention is to provide for the effective burning of a larger powder-charge behind a shot of increased Ordinarily a gun charge of powder given tofore been practicable, propelling forc weight than has hereand thus to give an e to the shot.

or cannon has its effective limited for a shot of given and a tail ged to project through a hole in the breech and cascabel and through the clamp, tail of the In this way,

larger and variable made to exert its which latter, shot, induces the breech and cascabe bearing friction down on the of said tail in l to retard the escape or by these means, a much than is otherwise attainable.

Referring to the A represent the w accompanyin alls of a gun,

The cascab verse hole, 0, through it clamp or plug, F, therethrough. This of Letters Patent N 0. 128,392, dated June 25, 1872.

B is the vent;

which hole may be countersunk back and front to prevent any scraping rapid discharge through the plug.

of the tail D during its G is .a lever, pivotedto the gun, and arranged to pass through a hole,

which is graduated, is fitted with operated by a or justment' along which it forms which is hung said screw,

a ball or weight,-k. In place of the single lever G a compound one, or sys' tem of levers, as

suffice,

vent the when the as described, an

but a stop is provided or projection which carries the plug or clamp tail of the shot By means of the plug F in Fig. 3, may be used, maller weight, It, will by the casting levers to prefrom falling too low is free of it. and its attachments, y desired amount of friction shown may be put upon the tail D of the shot in the cascabel and breech of the gun, according to the amount of powder-charge it is required to explode. Thus, dred' pounds, an

pounds of powder behind it in usual charge of twenty pounds, then the adjusted along the l on the weight k is the friction passes through t hundred pounds of the shot gives force to be set in motion.

overco As said charge of powder 118 if the shot weigh one hund it is desired to use sixty place of the tail of the shot where it he plug will be equal to two This added to the weight three hundred pounds as the me before the shot can be burned and exerts its force on the shot the latter moves for within the gun,

ward and draws the tail D and as soon as said tail is -neously therewith the resistance or friction 2 reason drawn beyond or out of the plug F the latteris drawn down by the weight 7t, and simultaand which will be equivalent to rerifling the gun, while the latter, having no rifling or grooves within it, is stronger, and the degree of rifling may be changed by substituting one clamping-plug for another.

What is here claimed, and desired to be secured by Letters Patent, is-

1. The combination of the friction producing device, applied in rear of the bore of the gun, a hole, I), through the breech or rear portion of the gun in direction of its length, and

due to the action of the clamp (here supposed to be two hundred pounds) is destroyed, when the shot immediately springs forward under the full force of the extra powder-charge at a rapid velocity through the remaining portion of the gun and out of it.

If desired the vent B may be dispensed with and the tailD of the shot made tubular and with transverse holes in it, for communicating fire to the powder-charge by means of rocket or fuse powder inserted in said hollow tail, and which may be ignited from the rear of the tail. Furthermore, instead of a solid shot, a shell may be used, and the hollow tail be made to act as a fuse for exploding the shell at any given point in its flight. Likewise the tail of the shot or shell may be rifled, and also the plug F, so as to throw rifled shot from' a smooth-bored gun; but in such case said tail and plug should be made of larger diameters. Under such an arrangement a new clampingplug may be substituted whenever necessary,

passage through said clamp and rear of the tion substantially as and for the purpose herein set forth.

2. The combination, with the friction clamp or plug 1? and hole I) in the gun, of a weighted lever made capable of adjustment as regards its load, essentially as and for the purposes described.
